Time, when you’re waiting for something you crave, moves gradually and then all at once. The Sentence, a new documentary premiering Monday on HBO, transmutes this strange, familiar tempo into affecting cinematic form as it chronicles the unjust jail time served by Cindy Shank, a wife and mother of three. “She went to prison. They did the time,” the film’s tagline reads. It’s true: Cindy may have been the one sentenced to 15 years away, but the reverberations of her absence on her parents, siblings, husband and most of all her three daughters—all ages five and below when Cindy was taken away—were equally devastating.
